kept in the heap overnight in the field, and hauled to the barn at 

 9 a. m., was stored in one of the large bays in the station barn. The 

 hay had been very dry when raked. On February 18, 1899, the 

 hay weighed 5,117 pounds, showing a shrinkage of 646 pounds, 

 equivalent to 1 1 .2 per cent in 7 months. 



(12) Investigations made at the Kansas station 9 led to the con- 

 clusion that, as stacked, well-cured alfalfa will contain from 16 to 24 

 per cent of moisture, fully air-dried hay from the stack or mow 

 should contain 10 to 12 per cent of moisture, and the average shrink- 

 age of well-cured alfalfa hay put into the stack or mow, by loss of 

 moisture, should not be greater than 10 per cent. 



(13) At the Missouri station 10 5,678 pounds of timothy was stacked 

 as drawn from the field. When weighed the following spring, it 

 had shrunk to 4,972 pounds, a loss of about 12.7 per cent. 



(14) At the Kansas station (see footnote 7, p. 5) orchard grass 

 hay lost 9.01 per cent and bluegrass hay lost 10.05 per cent in the 

 mow in 6 months. 



(15) At the same station (see footnote 7, p. 5) a bag containing 

 prairie hay buried in the mow for 6 months lost 7.33 per cent. 



(16) At the Michigan station (see footnote 8, p. 5) on June 27, 

 1896, 5 tons of very dry timothy was drawn from the field and, 

 after weighing, was placed in the barn in a mow, separated from the 

 rest of the hay in the barn. It was, later, temporarily covered with 

 grain in the straw. Six months later, on January 26, it was removed 

 and found to have lost 684 pounds, or nearly 7 per cent. 



(17) At the Kansas station (see footnote 7, p. 5) a mixture of 

 orchard grass, clover, and a little timothy, buried in a bag in the mow 

 for 6 months, lost 5.71 per cent. 



(18) At the Michigan station (see footnote 8, p. 5) in July, 1897, 

 1,100 pounds of clover hay, containing a little timothy, was put in 

 the barn directly from the windrow, being unusually dry for hauling 

 from the field. It was reweighed November 12 following, when it 

 showed a loss of but 398 pounds, or 3.6 per cent. 



(19) At the Utah station (see footnote 6, p. 5) a ton of clover 

 hay put in the barn July 15, 1892, and removed April 20 following, 

 lost 75 pounds, or 3.75 per cent. 



(20) At the Kansas station (see footnote 7 p. 5) three tests with 

 prairie hay buried in the mow for 6 months showed that the loss 

 amounted to about 3.50 per cent. 



(21) At the same station (see footnote 7, p. 5) one bag of prairie 

 hay, buried in the mow for 6 months, lost only 0.58 per cent. In 

 another case the loss amounted to but 0.29 per cent.
